Molten chloride salts have received considerable research attention as potential nuclear fuel and coolant candidates for molten salt reactors. However, there are several challenges, especially for structural materials due to the selective dissolution of chromium (Cr) in the molten chloride salts environment. Understanding the compatibility of uranium (U), which is used as nuclear fuel in molten salt reactors, with Cr in molten chloride salts is critical for designing the molten salt reactor structure. Therefore, in this study, the cyclic voltammetry (CV) was used to investigate the electrochemical behaviors of U and Cr. The diffusion coefficients and formal potentials were obtained. The electrochemical properties of uranium and chromium were investigated by CV in molten NaCl-MgCl2 salt at 600°C. Tungsten rods for working and counter electrode, and Ag/AgCl for reference electrode were utilized in this experiment. UCl3 made from the chemical dissolution of U rods and CrCl2 (Sigma-Aldrich, 99.99%) were used. Diffusion coefficients (D) of U and Cr were calculated by measuring reduction peak current of U3+/U and Cr2+/Cr from CV curves and using the Berzins-Delahay equation; D (U3+/U) = 3.0×10-5 cm2s-1 and D (Cr2+/Cr) = 3.3×10-5 cm2s-1. The formal potentials were also calculated by using the reduction peak potential obtained from CV results; E0’ (U3+/U) = -1.173 V and E0’ (Cr2+/Cr) = -0.321 V. The ionization tendency was investigated by comparing each reduction peak potential. The reduction peak potential Ep,c was increasing order of Ep,c (U3+/U) < Ep,c (Cr2+/Cr) < Ep,c (U4+/U3+). It can be seen that in the presence of U4+ and Cr metals, the Cr in the alloy can dissolve into Cr2+, but in the presence of U3+ and Cr metals, the Cr in the alloy does not dissolve into Cr2+. By analyzing the CV curve, diffusion coefficients and formal standard potentials were obtained. The result of comparing reduction peak potentials suggests that the nuclear fuel using U4+ should be inhibited to prevent the selective dissolution of Cr.

The ultimate objective of deep geological repositories is to achieve complete segregation of hazardous radioactive waste from the biosphere. Thus, given the possibility of leaks in the distant future, it is crucial to evaluate the capability of clay minerals to fulfill their promising role as both engineered and natural barriers. Selenium-79, a long-lived fission product originating from uranium- 235, holds significant importance due to its high mobility resulting from the predominant anionic form of selenium. To investigate the retardation behaviors of Se(IV) in clay media by sorption, a series of batch sorption experiments were conducted. The batch samples consisted of Se(IV) ions dissolved in 0.1 M NaCl solutions, along with clay minerals including kaolinite, montmorillonite, and illite-smectite mixed layers. The pH of the samples was also varied, reflecting the shift in the predominant selenium species from selenious acid to selenite ion as the environment can shift from slightly acidic to alkaline conditions. This alteration in pH concurrently promotes the competition of hydroxide ions for Se(IV) sorption on the mineral surface as the pH increases and impedes the selective attachment of selenium. The acquired experimental data were fitted through Langmuir and Freundlich sorption isotherms. From the Freundlich fit data, the distribution coefficient values of Se(IV) for kaolinite, montmorillonite, and illite-smectite mixed layer were derived, which exhibited a clear decrease from 91, 110, 62 L/kg at a pH of 3.2 to 16, 6.3, 12 L/kg at a pH of 7.5, respectively. These values derived over the pH range provide quantitative guidance essential for the safety assessment of clay mineral barriers, contributing to a more informed site selection process for deep geological repositories.

This program aims to build a specialized and converged educational platform for the training of students in the back-end nuclear fuel cycle and cultivate integrated human resources encompassing majors, generations, and fields. To achieve this, we have established an infrastructure for integrated education and training in the radiochemistry and back-end nuclear fuel cycle and operated specialized educational courses linked with special lectures, experimental practices, and field trips. Firstly, to construct an integrated educational and training infrastructure for the back-end nuclear fuel cycle, we formed a committee of experts from both inside and outside the institution and built an advanced radiochemistry laboratory equipped with physical and chemical analysis instruments. Through a comprehensive educational program involving theory, experiments, and discussions, we have established an integrated curriculum across adjacent majors and interdisciplinary studies. We also operate short-term education and experimental training programs (e.g., summer and winter schools for the back-end nuclear fuel cycle). Secondly, the program has connected leading researchers domestically and internationally, as well as the next generation of scholars. The program offers long-term educational opportunities and internships targeting both undergraduate and graduate students. To support this, we continuously offer expert colloquiums and individual research internships. Through regular committee meetings and workshops, we focus on nurturing the integrated talents necessary for the back-end nuclear fuel cycle. Through this program, students from various fields are being trained as competent integrated human resources capable of addressing various issues in the back-end nuclear fuel cycle. It is expected that this will enable us to supply specialized technical personnel in the back-end nuclear field in line with mid-to-long-term demands.

본 연구는 OECD TG No. 458, 22Rv1/MMTV_GR-KO 전사 활성화 분석법을 포함한 세포 기반 분석법을 사용하 여 식품 및 생활용품에 포함된 파라벤과 트리클로산의 인 간 안드로겐 수용체를 매개하는 내분비계 교란 가능성을 확인하는 것을 목표로 한다. 4가지 파라벤(메틸-, 에틸-, 프 로필-, 부틸-)은 OECD TG No.458에서 AR 길항제로 확 인된 반면, 파라벤의 AR 길항 효과는 S9 간 분획물이 있 는 경우 나타나지 않았다. 트리클로산 역시 AR 길항제로 분류되었으며, 트리클로산에 의해 유도된 AR 길항 효과 는 S9 간 분획물이 존재할 때 제 1상+2상 대사에서 유의 하게 감소되었다. 파라벤과 트리클로산에 의해 유도되는 AR 길항 기전은 세포질 내 AR 이량화를 차단하여, 리간 드 결합 AR이 핵으로의 전위를 억제함으로써 AR 매개 내분비 교란 효과를 나타냈다. 이러한 결과는 4가지 파라 벤과 트리클로산이 AR 이량화 저해를 통한 AR 길항 효 과를 나타내는 AR 매개 내분비 교란 가능성을 가지고 있 으나, 간 대사 효소가 존재할 경우 내분비 교란 효과는 감 소됨을 시사한다.

Studies on automatic scoring systems in writing assessments have also evaluated the relationship between human and machine scores for the reliability of automated essay scoring systems. This study investigated the magnitudes of indices for inter-rater agreement and discrepancy, especially regarding human and machine scoring, in writing assessment. The mean of the overall population correlation between automated and human scoring in essay writing was .78. The overall common d effect size was 0.001. Results from this meta-analysis indicated a strong relationship with no discrepancies between automated and human scoring. Both the I2 and Q values suggested that the population correlation values studied seemed to be heterogeneous, in contrast to homogenous d effect sizes. Therefore, it is necessary to investigate the sources of the between-studies variations for r correlations. Practical implications for ways of reporting results of automatic-scoring systems research and limitations of the study are also discussed.

본 연구의 목적은 신석기 시대 존재했던 여성 신이 지녔던 생명력, 평등성, 포용성, 그리고 이타성의 가치와 인류 문화원형의 상징성을 파악하고 복원 필요성을 제시하고자 하는 것이다. 현대사회는 자연 생태계 파괴, 전쟁, 그리고 환경 오염이 진행되고 있는 시점이다. 따라서 생명의 존엄성으로 대표되는 여신의 상징적 가치 회복은 중요한 문제이다. 생명의 가치를 대변하는 여신문화는 현대사회의 미래지향적 가치와 연결성을 지니기 때문이다. 제주도는 여신문화의 회복이 요구되는 시점에서 다양한 여신 관련 신화들이 존재한다는 점에서 특별한 의미가 있다. 제주도 여신 신화 및 문화는 신성성, 생명성, 그리고 주체적 여성의 모습을 제시하고 있다. 제주도의 여신문화는 인간과 자연의 조화뿐만 아니라 인류가 상실했던 여신 원형 문화라는 점에서 매우 중요한 의미를 갖고 보존 필요성이 요구되는 유산이라고 할 수 있다.

인간이라면 누구나 보호받아야 할 인권을 가지며, 오늘날 인권 보호에 관한 중요성은 사회 모든 분야에서 강조되고 있다. 산업 계에서도 인권 경영을 위하여 인권교육을 시행하고, 인권침해 대응 체계를 마련하는 등 근로자의 인권을 보호하기 위한 활동을 수행하고 있다. 그러나 선박에 승선하고 있는 선원은 그 폐쇄적인 환경과 특수한 근로조건으로 인하여 인권 보호에 사각지대에 놓여 있는 경우가 많다. 특히, 실습선원을 비롯한 초급 선원을 중심으로 다수의 인권침해 사례가 발견되고 있으며, 관련 실태조사나 연구가 타 직군에 비하 여 미흡한 현실이다. 인간의 기본권을 제한받는 직업은 누구에게도 선망의 대상이 될 수 없으며, 해기사를 꿈꾸는 실습선원의 인권 보호 와 권익 신장은 해기인력 확보와 선원직 매력화를 위하여 선행되어야 할 과제이다. 이 연구에서는 실습선원을 대상으로 한 인권 실태조 사 결과와 인권침해 사례를 바탕으로 시사점과 문제점을 도출하였고, 그에 대한 개선방안을 제시하였다. 실습선원은 승선 전 선상에서의 인권침해에 대하여 매우 부정적 인식을 가지고 있었으나, 실제로 승선 후 선내 인권침해에 대한 부정적 인식은 완화된 것으로 나타났다. 실습선원이 승선 전 불필요한 두려움과 공포를 가지는 것으로 확인되었으며, 이에 대한 개선방안으로 실습선원의 지위에 관한 법제도 마 련, 비물리적 인권침해 완화를 위한 조치, 인권침해 처리 절차와 대응 체계 개선, 인권교육의 실효성 확보 등을 제시하였다.

본 연구목적은 청소년의 인권인식에 미치는 의사결정시 부모태도, 학 교생활만족도, 자아존중감 변인 간의 구조적 영향관계를 확인하는 것이 다. 한국청소년정책연구원에서 시행한 「아동·청소년 인권실태조사」의 2020년 청소년인 고등학생 2,994명을 연구대상자로 선정하였다. Stata 16을 활용하여 빈도분석, 기술통계, 상관관계분석, 구조방정식 모델 분석 을 수행하였다. 첫째, 청소년의 의사결정시 부모태도는 자아존중감과 인 권인식에 유의한 정적인 영향을 주었다. 둘째, 학교생활만족도는 자아존 중감과 인권인식에 정적인 영향을 미쳤다. 셋째, 자아존중감은 인권인식 에 유의한 정적인 영향을 미치는 것으로 확인되었다. 넷째, 의사결정시 부모태도는 자아존중감을 부분매개로 하여 인권인식에 정적인 영향을 주 었고, 학교생활만족도는 자아존중감을 부분매개로 하여 인권인식에 정적 인 영향을 나타내었다. 본 연구는 청소년의 인권인식 증진을 위해서 교 육적 경험 측면에서 청소년들에게 무엇이 필요하고 어떠한 제도가 교육 현장에서 시행 및 개선되어야 하는지 고민 및 논의하였다는 관점에서 의 미가 있다고 사료된다.

이 논문은 결정론적인 역사적 순환에서 인간이 개입하고 참여할 수 있는 여러 방식을 세 편의 수태고지 시를 중심으로 다시 읽는다. 예이츠의 역사 체계에서 역사 순환은 단순히 인간의 외부에서 부과되는 것뿐만 아니라 인간의 여러 잠재력과의 상호작용을 통해 진행한다. ｢레다와 백조｣는 그리스 문명의 탄생이 레다라는 인간의 실존과 몸을 통해 매개됨을 보여준다. ｢한 희곡 작품에서 발췌한 두 편의 노래｣는 인간의 자유가 실패에도 불구하고 압도적인 역사 순환의 힘에 저항하는 것에서 표출됨을 드러낸다. ｢재림｣은 역사 순환이 역사에 대한 사실 그 자체가 역사의 사실이 되는 것이 아니라 인간의 관점과 문제의식에 따라 해석하여 재구성된다는 예이츠의 확신에 맞닿아 있다. 세 편의 수태고지 시에서 예이츠는 역사의 순환과 인간의 잠재력—몸, 실존, 자유의지, 해석 등—사이의 대립을 화해로 전환하는데, 이는 역사의 순환을 재배열하고 의미를 부여하려는 인간의 투쟁으로 매개된다.

인간구성의 24원리의 집합체는 다섯 가지 지각기관, 다섯 가지 행동기관, 감각적 마음 (manas)과 다섯 가지 미세 요소의 16가지 요소와 다섯 가지 거친 요소, 이기적 마음 (ahaṁkāra), 지성적 마음(buddhi)과 미현현(avyakta) 등 8가지 물질원리(aṣṭa-prakṛti)로 이루 어졌다. 감각적 마음의 정의는 ‘감각적 마음은 내적 감각기관’이다. 감각적 마음은 감각기관 의 도움과 함께 인식의 대상을 인식한다. 감각적 마음은 무의식적이지만 행위를 가지고 있 다. 그렇지만 감각적 마음은 개인적 자아와 결합하기 전까지는 행위를 할 수 없다. 이기적 마음은 미현현, 지성적 마음, 다섯 가지 미세요소 등과 함께 여덟 가지 창조의 원천 가운데 하나이다. 이기적 마음은 지성적 마음의 기능에 포함된다. 지성적 마음이 불균등하게 판단 하면 모든 도샤(doṣas)가 손상되는데 그것의 원인은 이기적 마음이 아니라 감각적 마음이 원인이라고 말한다. ‘최고의 자아(paramātman/Ātman)’은 시작도 없으며, 24가지 요소의 모 든 속성과 행동 등은 자아에 의해 목격되며, 그가 원하는 대로 행위를 할 수 있다. 그러나 [최고의] 자아는 자신의 행동의 결과를 향수할 의무가 있다. 자아는 ‘자아’, 또는 번역자들처 럼 ‘최고의 자아’의 의미로 ‘지각력을 지닌 뿌루샤’와는 차원이 다른 것으로 이해된다. 이것 은 고전 상캬 체계에서 보면, 모든 사실이 그렇다고는 단정을 지을 수는 없지만, 굳이 대조 하여 비교하면 뿌루샤는 근본 물질원리인 쁘라끄리띠(prakṛti)의 역할과 비슷하고, 자아(ātman)는 뿌루샤의 역할과 비슷한 것으로 보인다. 그렇다고 아유르베다가 이원론이라는 의미는 아니다.

With the dramatic advance in artificial intelligence, the use of an AI anchor in the news industry is a subject of great interest. An AI anchor is a computer-generated news anchor that mimics the human voice, appearance, and facial expressions to present the news. As the focus of this study is to investigate how the news media utilize an AI anchor in the news program, the research questions are as follows: (1) What are the differences in news topics between AI and human anchors? (2) How does the viewership differ based on these topic choices, with a focus on the emotional impact?

Crowding is widely observed in various tourism contexts. Compared with natural scenic areas, theme parks have concrete boundaries and are physically, economically, or culturally separate from the surrounding area, it also brings problems with carrying capacity and visitor management. Data shows that China has become a critical theme park market, and crowding has become a major problem for theme park operators in China. This study examined the effects of human crowding on visitors' emotions, satisfaction, and behavioral intentions using the M-R model as a framework. The investigations were conducted in Shanghai Disneyland and Zhuhai Chimelong Ocean Kingdom, 295 and 410 valid questionnaires were collected respectively.

In the current study, we directly measure consumers’ physiological responses (i.e., brain waves via electroencephalogram [EEG]) to advertising stimuli (digital storyteller vs. human storyteller) to confirm the narrative transportation process of storytelling immersion.

Artificial intelligence (AI) is transforming healthcare, yet little is known about how consumers experience and make decisions regarding follow-up care with medical AI. We take an interdisciplinary approach combining behavioral research and neuroscience to examine how anthropomorphism and personalization influence well-being and follow-up decisions. Study 1 found that consumers felt well-being after interacting with a highly personalized interaction, whether human or AI doctor. However, they preferred follow-up visits with the human doctor. Empathy mediated these effects. Study 2 used fMRI to show that the anterior cingulate cortex had greater activation when interacting with the human doctor, indicating more emotional processing and conflict resolution. These findings suggest that medical AI cannot currently replace human doctors, who remain vital for actual medical consultations and treatment. However, consumers viewed AI doctors positively and expressed a belief that AI will enhance well-being. By integrating neuroscience, this research provides biological evidence complementing behavioral findings.

Artificial intelligence (AI) technology is recognized as essential in the 4th industrial revolution (Schwab, 2017), which is capable of interacting with the environment and processing and transforming data information to inform goal-directed behavior (Paschen, Kietzmann, & Kietzmann, 2019). Due to the advances in intelligent systems and the incorporation of AI agents in smart devices, more than eight billion digital voice assistants will be used globally by 2024 (Thormundsson, 2022; Gilkson & Woolley, 2020). For successful and positive consumer-brand relationships, constructs such as trust, satisfaction, and commitment are vital (Garbarino & Johnson, 1999; Nyadzayo & Khajehzadehb, 2016). Unlike humans, Artificial intelligence agents could achieve relationship marketing engagement by encouraging users to anthropomorphize the other parties in their technology-mediated interactions, such as applications like chatbots, virtual assistants, and service robots (Steinhoff et al., 2019). Those applications can also use humanoid traits to engage customers in organizations (van Doorn et al., 2017).

Robo-advisors are gaining momentum, as they aim to provide personalized and low-cost financial advice (Jung et al., 2019). However, the effectiveness of robo-advisory is bounded by the lack of trust (Jung et al. 2018). Anthropomorphism or robo-advisor resemblance to a human (i.e., avatar, name, or gender) can remedy that. Indeed, robo-humanization can establish trust and impact on behavioral intents toward the advisory technology through social presence (Go & Sundar, 2019), warmth (Cyr et al., 2009), perceived expertise of the advisor (Qui & Benbasat, 2009), including perceived integrity and persuasiveness (Tan & Liew, 2020). Gender can amplify anthropomorphic cues and, thus, increase trust (Beldad et al., 2016). Finally, trust toward the technology is directly related to its adoption intent (Bruckes et al., 2019).

Digital humans integrating anthropomorphism into the performance and problem-solving features of AI offer innovative sources of insights and value that promotes a product, service, or brand. The purpose of this study is to investigate the effects of a digital human’s aura and anthropomorphism on perceived interactivity, attitude toward a brand, attitude toward a digital human, electronic word of mouth (eWOM) intention, and purchase intention. An entrenched digital human’s aura and anthropomorphism increase perceived interactivity, attitude toward a brand, attitude toward a digital human, eWOM intention, and purchase intention. This study contributes to the literature by clarifying the concept of the digital human’s aura and anthropomorphism and the relationships between perceived interactivity, attitude toward a brand, attitude toward a digital human, eWOM intention, and purchase intention.

Imagination plays a critical role in travel decision-making. Given the intangible nature of tourism products, tourists cannot directly experience and evaluate the tourism resources in advance. Thus, tourists must first mentally predict and imagine the future travel experiences and scenarios in the destination based on the marketing information (e.g., travel photo, promo video) and prior knowledge, then form their subjective evaluation of the travel product. This future-thinking process is called “mental simulation”. Stacks of research have shown that mental simulations positively affect travel behavior (Le et al., 2019). However, given that travel is a kind of novelty-seeking activity, tourists are usually not familiar with the destination environment and activities. The lack of prior knowledge might inhibit their mental simulation process, even if destination photos and videos are provided. Thus, how to effectively arouse tourists’ mental simulation of destination experience is an important question for effective tourism marketing.

The present study compared the effectiveness of virtual influencers (VIs) to human influencers through the theoretical lens of the uncanny valley and parasocial relationship using an online experiment. Specifically, we posited that highly humanlike VIs may evoke the feeling of the uncanny valley, as compared to human influencers or cartoonlike influencers, which, in turn, would act as a psychological barrier to building a parasocial relationship with the specific type of virtual influencer and decrease advertising attitude. The results indicated that people do feel the uncanniness from both highly humanlike and cartoonish influencers as compared to human influencers. This particular psychological experience negatively influenced the parasocial relationship, which, in turn, negatively affected the attitude toward a social media advertisement featuring the VIs. However, importantly, this effect was moderated by individual differences in anthropomorphism. This is one of the first studies that directly compared the effectiveness of different types of social media influencers in a rigorously designed experimental setting and expands the previous research on Vis, uncanny valley, and parasocial relationship. Both theoretical and managerial contributions of the study were discussed.

Considering the popularity of virtual influencer (VI) marketing while its effectiveness remains fully unexplored, there is a need of academic attention testing consumer responses to VIs in comparison with human influencer marketing. Hence, this study aims to fill this gap by comparing consumers’ perceptions of a human versus virtual influencer’s endorsement. Specifically, based on the construal level theory and psychological reactance, this study investigates how consumers differently evaluate human and virtual influencers’ endorsement motives, which may further influence their attitudes toward a brand, advertising (i.e., endorsement), and an influencer and purchase intentions. Additionally, the moderating role of the number of endorsements (single vs. multiple) and perceived innovativeness are examined.
